Subject: [Intel-gfx] [PATCH 06/30] KVM: x86: mark syntethic SMM vmexit as SVM_EXIT_SW
Date: Mon, 7 Feb 2022 17:28:23 +0200 [thread overview]
Message-ID: <20220207152847.836777-7-mlevitsk@redhat.com> (raw)
In-Reply-To: <20220207152847.836777-1-mlevitsk@redhat.com>
Use a dummy unused vmexit reason to mark the 'VM exit'
that is happening when we exit to handle SMM,
which is not a real VM exit.
This makes it a bit easier to read the KVM trace,
and avoids other potential problems.
